specific Embodiment approach

[0020] The present invention will be further described in detail below in conjunction with specific embodiments, which are explanations of the present invention rather than limitations.

[0021] Embodiments of the present invention adopt screened gold mine tailings in Hanyin area, Shaanxi Province as the main raw material. The screened gold mine tailings have removed muddy parts with smaller particle sizes, and these muddy parts have a great influence on the drying and drying of raw materials. The clarification of the high-temperature glass liquid and the stability of the glaze have adverse effects.

[0022] The chemical composition (mass fraction) of the screened gold mine tailings was analyzed as: SiO 2 60%;Al 2 o 3 18%; CaO1.12%; MgO5.83%; Fe 2 o 3 7.14%; Na 2 O3.73%; K 2 O4.82%; TiO 2 0.83%.

Embodiment 1

[0024] The preparation method of ceramic glaze of the present invention may further comprise the steps:

[0025] 1) In terms of mass fraction, mix the following raw materials: 52 parts of the screened gold mine tailings, 12 parts of quartz, 20 parts of calcite, 6 parts of borax, 2 parts of fluorite, ZnO2, Cr 2 o 3 2 parts, Sb 2 o 3 1 part; after mixing evenly and passing through a 60-mesh sieve, melt in a box-type silicon carbide rod resistance furnace at 1250-1350°C for 3-4 hours to obtain molten glass, and quench the molten glass to obtain block glaze;

[0026] 2) The block glaze is wet ball milled, and the slurry after ball milling is passed through a 200-mesh sieve to remove impurities, and the glaze slurry is obtained, and the concentration of the glaze slurry is controlled at 1.5g / ml;

[0027] 3) Apply the glaze slurry to the surface of the green body by brushing the glaze, dry it in an oven at 80°C until its moisture content is less than 1%, then fire it at 1150-1200...

Embodiment 2

[0030] The preparation method of ceramic glaze of the present invention may further comprise the steps:

[0031] 1) In terms of mass fraction, mix the following raw materials: 70 parts of the screened gold mine tailings, 5 parts of quartz, 25 parts of calcite, 7 parts of borax, 2.5 parts of fluorite, 2.5 parts of ZnO, Cr 2 o 3 5 parts, Sb 2 o 3 1.5 parts; after mixing evenly and passing through a 60-mesh sieve, melt in a box-type silicon carbide rod resistance furnace at 1300-1350°C for 3-4 hours to obtain molten glass, and quench the molten glass to obtain frit glaze;

[0032] 2) The block glaze is wet ball milled, and the slurry after ball milling is passed through a 200-mesh sieve to remove impurities, and the glaze slurry is obtained, and the concentration of the glaze slurry is controlled at 1.6g / ml;

[0033] 3) Apply the glaze slurry to the surface of the body by brushing the glaze, dry it in an oven at 80°C until its moisture content is less than 1%, and then fire it...

Abstract

The invention discloses a method for preparing a ceramic glaze by using gold-tailings, belonging to the technical field of ceramic glaze processing. The method comprises the following steps of: weighting the following raw materials in parts by mass: 50-85 parts of gold-tailings, 5-20 parts of quartz, 20-30 parts of calcite, 5-10 parts of borax, 0-3 parts of fluorite, 0-8 parts of Li2CO3, 0-6 parts of Fe2O3, 0-8 parts of Cr2O3, 0-3 parts of ZnO, 0-2 parts of MnO2, 0-2 parts of CuO, 0-6 parts of Co2O3 and 0.5-2 parts of Sb2O3, and sufficiently mixing the raw materials; sieving by using a 60-80-mesh sieve after uniformly mixing the raw materials, then smelting at the temperature of 1200-1400 DEG C for 2-4h, and quenching with water to obtain a massive glaze; and ball-milling the massive glaze by using a wet process, then sieving to remove impurities to obtain a glaze slip, applying the glaze slip on the surface of a blank, firing, and then cooling to obtain the ceramic glaze. The method for preparing the ceramic glaze by using the gold-tailings as the main raw materials, disclosed by the invention, has the advantages that the glaze is prepared from the gold-tailings instead of natural raw materials, the resource is developed secondarily, the wastes are turned into the things of value, meanwhile, the environment pollution is reduced, and the production cost of the ceramic glaze is reduced.

Description

technical field [0001] The invention belongs to the technical field of ceramic glaze processing, and in particular relates to a method for preparing ceramic glaze by using gold ore tailings. Background technique [0002] With the development of production technology, more and more mineral resources have been exploited, and the available mineral resources have decreased rapidly, and the contradiction between resource demand and resource shortage has become increasingly prominent. At the same time, during the mining of mineral resources, a large amount of tailings resources are accumulated, which pollutes the environment, poses a serious threat to human survival, and causes a waste of mineral resources. Therefore, the effective development and utilization of tailings resources is an important way to reduce the pressure of environmental pollution and alleviate the shortage of mineral resources, and has huge economic and social benefits. [0003] The preparation of ceramic glaz...
